A full butted joint structure of a connector lug between the side frame and the cross beam of the bogie is provided. The side frame is connected to the cross beam (1) by a connecting seat (2). The side frame connecting end and the side frame inside vertical plate (5) forms a plate-plate abutting joint structure, and the cross beam connecting end and the cross beam (1) form a tube-tube abutting joint structure. The welding technique includes the following steps: the connecting seat (2) is welded to the cross beam tube; the cross beam unit is welded; the connecting seat (2) is welded to the side frame inside right plate (5) and the guide pillars (3); the side frame strengthen partition plate (7) is welded to an upper cover plate (4); the frame body is welded. The new abutting joint realizes a full butted joint between the side frame and the cross beam of the bogie. The stress concentration is reduced in the welding point. The welding charge, the welding residual stress and deforming reach the minimum. The loading-carrying and anti-fatigue ability become greater.
